In the history of the domestic automotive industry, there were many folk cars for commercial use. Some of them are especially popular. For example, this light vehicle GAZ-33021, despite being produced from 1994 to 2010, remains one of the most popular on the Russian market.

The need for such a machine began to dictate market relations, which began their revival and development. Trade, and other activities, constantly needed the transportation of small-sized cargo.

The GAZ production group became one of the first automotive companies that listened to the requirements and launched GAZelle trucks on the booming market. Then the GAZ-33021 car appeared, which very quickly occupied the niche that had been empty for a long time, and immediately turned into the main assistant for everyone who was engaged in small business.

The appearance and dimensions of this model are quite compact. The truck turned out to be very maneuverable and perfectly suitable for domestic roads and cities with narrow entrances to warehouses, shops and other infrastructure facilities.

The GAZ-33021 car is a modification of the large 3302 family. The body design here is distinguished by improved aerodynamic characteristics that are typical for the entire series. The cabin is made of solid metal. Glazing of its panoramic type and quite large. The bumper was made of plastic and was practical. At first, GAZelles were produced with a rather nondescript grille and simple headlights. rectangular shape. However, then they were replaced by elements more suitable for the time. So, the headlights got a more teardrop shape.

Three people could sit in the cabin of the GAZ-33021 car. At the beginning of the release, the interior was rather weak in terms of ergonomic capabilities, but in later versions, the angular and uninteresting shapes of the dashboard were slightly diversified. So, after restyling, the dashboard acquired a more modern shape, and they began to manufacture it using materials more High Quality. The specialists did a great job on it - the ergonomic characteristics improved noticeably, and this allowed the car to become not only a very profitable purchase, but also a very convenient truck to drive.

small commercial models GAZ-33021 were equipped with an onboard platform for the transport of goods and awnings to it. The awning rested on a metal frame. The platform was 3056 mm long and 1943 mm wide.

Additionally, it was equipped with folding sides on the side, as well as a tailgate.

If we talk about dimensions, then the dimensions of the car are completely 5440 mm in length, of which 2900 is the length of the wheelbase, 990 mm was given to the front overhang and 1550 mm to the rear overhang. The cab has a width of 1966 mm. The entire truck, measured along the sides, is 2098 mm wide. Height measured by top point awning, is 2570 mm. The cabin is 2120 mm high. Ground clearance under the crankcase on the rear axle is 170 mm. You can see what the GAZ-33021 car looks like.

The photo will allow you to visually assess the dimensions.

Concerning weight characteristics, then the curb weight of this vehicle is 1850 kg.

Full mass is equal to 3.5 tons. At the same time, it must be said that maximum load on the front axle for the GAZelle is 1200 kg, on the rear axle you can load 2300 kg. The truck can carry up to 1.5 tons of various cargoes.

For a group trucks Model 3302 engineers have prepared a huge range of the most various engines. Many of them have been in use for many years, and some have gone only a little. At the beginning, trucks were supplied with 4-cylinder in-line gasoline ZMZ engines-4025. The power of this unit was 90 hp. Then ZMZ-4026 appeared with power characteristics of 100 "horses". And then they began to install new gasoline and diesel units. The most popular was the gasoline ZMZ-405, which was used on some modifications.

For GAZ-33021 cars, the engine, depending on the modification, could be gasoline ZMZ-4026 or UMZ-4216. There is no special need to talk about them - everyone has known about them for a long time.

UMZ-4216 was one of the most popular units among motorists.

It was also 4-cylinder. Its working volume was 2.9 liters. This unit was distinguished by a redesigned and significantly the best system injection. So, its maximum power characteristics were 120 Horse power. The maximum torque was 235 Nm at 2500 rpm crankshaft. The main advantage of this unit is that it could work with gas equipment.

All power units worked in tandem with the only 5-speed gearbox for the series. It was distinguished by three-shaft synchronization. With the motor, the box worked through a friction single-disk dry clutch. GAZ-33021, and other versions, was equipped with a hydraulic clutch drive.

Any modification in the 3302 family was based on a frame chassis.

Suspension system - what's behind, what's ahead - leaf spring, dependent type. It was supplemented hydraulic shock absorbers, also on rear axle anti-roll bar was installed. For GAZ-33021, a typical 4x2 wheel arrangement and rear-wheel drive were used.

The brakes in models from this family were a dual-circuit system with a hydraulic drive and a vacuum booster. Disc-based mechanisms were installed in front, while the most common drum brakes were installed at the back. Parking brake powered by a cable.

In the steering, they used the already traditional solution based on a screw and nut, and additionally equipped with a hydraulic booster control.

Unfortunately, the release of these commercial vehicles was discontinued in 2010.

The only thing left of the GAZ-33021 is the photos that you can see, well, used trucks on the secondary market.

GAZ engineers introduced GAZelle Business as a replacement. This is the second major upgrade in history. The car was equipped with imported components, but this did not affect the final cost. As far as innovations are concerned, master cylinder brakes, as well as both clutch cylinders. They have a common tank for liquid, and refilling it is now much easier. Also, the owners speak well of the hydraulic booster, because the old one was leaking shamelessly.

But, despite this, the old GAZelles still drive back and forth on our roads, working for the benefit of small businesses. And they will leave the market not so soon, as they are still used.

So, we found out what technical characteristics, interior and appearance the GAZ-33021 car has.

Students, graduate students, young scientists who use the knowledge base in their studies and work will be very grateful to you.

INTRODUCTION

Road transport, unlike other modes Vehicle is the most massive and convenient for the transportation of goods and passengers over relatively short distances. He possesses greater maneuverability, good adaptability and cross-country ability in various climatic and biographical conditions.

Road transport plays important role V transport system countries. The work of road transport ensures the normal functioning of enterprises. Over 80% of the volume of all transported goods falls on this type of transport, it is the road delivery that is the beginning and end of any transportation (rail, sea, air). Every day, buses and cars transport tens of millions of people.

Increasing the reliability of the car and reducing the cost of their maintenance are one of the most important tasks of the national economy. In order to solve this problem, vehicle manufacturers have established standards Maintenance and repair taking into account operation.

The trouble-free operation of the car largely depends on the timely and high-quality maintenance.

Maintenance is designed to keep vehicles in good working order. appearance. To reduce the intensive wear of parts, as well as to identify failures and malfunctions in order to eliminate them in a timely manner.

Maintenance is a preventive measure, carried out in a planned manner after a certain mileage or service life. Due to untimely or poor-quality maintenance, rapid wear units and engine components, as well as increasing the likelihood of vehicle breakdowns.

Course design - component educational process at the final stage of specialist training. In the process of course design, I must consolidate, deepen and generalize knowledge in the field and technology of maintenance and current repair cars and engines, develop skills independent work for solving practical problems in solving industrial practical issues. The course project contains various work of progressive technology and organization of workers in production areas.

3. SPECIAL PART

GAZ-33021 "Gazelle"

Russian cars in last years not so often found on the roads of our country. Imported BMWs, Toyotas, Mercedes, Ferraris and Volkswagens are replacing the products of the domestic auto industry. Of course, every car owner wants to have a car that is more reliable, more comfortable and cooler. Therefore, lovers of fast and luxurious driving invest in Western "cars", not really thinking about what and Russian manufacturer sometimes produces reliable and comfortable cars. And here the question arises: "Is it really so? Is it really that in such a civilized country as Russia, there are no good cars of their own?" Of course have. I must say that our cars are no worse than the notorious "Japanese". One has only to look carefully at the manufacturers, study all the details and choose a suitable Russian car for yourself.

One of the leaders is the GAZ-33021, which is worth paying special attention to. Such a machine can well boast of its qualities on Russian roads, and in terms of working life is ahead of many imported models. For the price, this mini-locomotive is an order of magnitude lower than its foreign counterparts. The release of "Gazelle" began in 1994 on famous factory OAO GAZ. Today, the car has already undergone about ten changes and modifications. What can be said and told about such a worthy brand as GAZ-33021? The technical characteristics of this car deserve special attention. The engine of this model is reliable and durable, especially when traveling on long distance. Old engines ZMZ-4025 and ZMZ-4026 are unpretentious to fuel and are very easy to repair. The new UMZ-4215 engines are more modified and have a number of additional advantages, for example, the cylinder block is made of aluminum alloy and is integral with the upper part of the crankcase. You can talk about the merits of the transmission, chassis and suspension for a very long time. They are reliable, durable in time and also easy to repair. Crankshaft cast from ductile iron. And, you can’t argue here, its quality is on highest level. The main braking system of the front wheels of the car is disc, and the rear wheels are drum. There is a spare brake system, which several times increases the safety of driving. On top of that, there is a mechanical cable-actuated parking brake system. It is connected to the rear wheel brakes. Therefore, the level of brake failure is kept to a minimum. Also applies contactless system ignition. It speaks of fire safety measures. Perhaps the only weak point GAZ-33021 are springs. Need to do it from time to time anti-corrosion coating these parts of the machine, otherwise they fail and break. Apparently, our manufacturers save on zinc coating of shock absorbers. But this is not a problem either. There are a lot of spare parts for this station wagon. It is always possible to buy any spare parts without any problems and it is easy to make even major repairs.

The following advantages of the GAZ-33021 include suitability for operation in different climatic conditions. Low temperatures, poor visibility and uneven roads, all this seems to be nothing for our Gazelle. Everyone chooses the level of comfort for himself. And here this model has proven itself with better side. It is used in cargo transportation, usually the carrying capacity reaches 3 tons. If you decide to purchase passenger minibus, That this car can be used for commercial purposes, for example, as a fixed-route taxi. And also GAZ-33021 serves in the Ministry of Health, the Ministry of Emergency Situations and other government agencies.

To ensure the reliability and performance of the car, it is necessary to carry out its maintenance in a timely manner and in the proper amount.

During disassembly and assembly work and repair of vehicle units, it is required special set tool. Therefore, special large and small sets (sets) of such tools are produced for car mechanics.

The kit includes: wrench open and socket (open-end) double-sided wrenches, overhead (ring) wrenches, a balloon wrench, a hammer, a chisel, a barb, a hinged head with an extension, simple and Phillips screwdrivers, a wrench for studs, special keys(for support pins, cylinder heads, spark plugs, etc.), torque handle with a set of heads different sizes, brace, mounting blade, pliers. To perform dismantling and assembly work of diesel engines, a special set of keys (OR-15727) is required.

When disassembling mechanisms or assemblies, pullers are used to remove bearings, gears and other parts. Their use facilitates and accelerates the disassembly process and ensures the safety of the pressed parts.

Pullers are universal and special. Universal pullers allow you to remove parts that are different in size and shape, therefore, taking into account the fact that different brands of vehicles are serviced at the overhaul site, a set of universal pullers (SU-13554) is required.

When performing disassembly and assembly work, stands and devices are used to which the units and components of the car are attached. The projected engine, gearbox and clutch overhaul site serves VAZ, GAZ, ZIL, KamAZ, MAZ, URAL, UAZ vehicles, therefore, universal dismantling and assembly stands are required to perform engine, gearbox and clutch overhaul.

From the entire range this equipment only the stand for disassembly-assembly of ZIL, ZMZ, VAZ, AZLK, KamAZ, YaMZ engines (manual) brand R-770, the universal stand for disassembly-assembly of gearboxes brand BS-09-000 and the stand for assembly and adjustment of clutches universal brand R are suitable -746.

After assembly, the engine must be run in and its operation checked, therefore, an engine test stand is necessary to perform these works.

From the entire list of equipment offered domestic producers, only the universal test stand of the KS-276-031 brand is suitable.

To move the vehicle units around the site, a trolley is required for transporting units with a load capacity of at least 350 kg. To carry out repair work, a metal two-pedestal workbench is required. Racks and shelves are required for temporary storage of engine, gearbox and clutch parts, and a tool cabinet is required for tool storage.

4. SAFETY OF LIFE IN PRODUCTION

1. Organization of work to create healthy and safe working conditions.

The health and safety of working conditions depends on the timely completion of training in labor protection (OHS) and safety (OHS).

Upon admission to the enterprise, an introductory briefing is carried out with the worker. It describes all the features of the enterprise, including those that pose a danger. An entry is made in the log when and to whom the introductory briefing was carried out and the instructed person puts his signature in the reporting log that he was instructed.

The introductory briefing is carried out by the safety engineer of the given enterprise and puts a mark in the worker's book that the briefing has been completed. After the introductory briefing, the worker is given a briefing at the workplace. It is carried out by the master of this site. Occupational health and safety briefing at the workplace is carried out once a quarter, and the worker signs in the log book for each briefing conducted with him.

Briefing at the workplace includes the features of this site, factors that pose a threat to health and various dangerous devices and assemblies (crane beams, hoists, etc.).

There are also unscheduled briefings, which are carried out after an accident or a serious violation of health and safety.

2. Instructions for labor protection during execution technical process.

When developing new technologies for the repair and maintenance of agricultural machinery, the safety of workers should be ensured by:

Elimination of direct contact of workers with raw materials, blanks, semi-finished products, connecting products, units, traumatic units, elements and production waste that have a dangerous and harmful effect;

Replacement of technological processes and operations in which dangerous and harmful production factors are constantly operating, processes and operations in which there are no or do not exceed the maximum permissible levels;

Integrated mechanization, automation of processes and operations when it is impossible to eliminate dangerous and harmful production factors from the technical process;

Sealing equipment or creating isolated rooms with increased (excessive compared to atmospheric) air pressure;

Indication of the list of means of collective and personal protection workers;

Instructions on the use of protective equipment and devices that automatically eliminate the impact of hazardous factors on workers, including in the event of an accident;

Protection from possible negative effects of natural nature and weather conditions.

When using new initial data of materials, preparations in the technological process, as well as when intermediate substances with dangerous and harmful factors are formed after their use, regulatory documents should be developed in order to organize training for workers in a safe way of performing work and providing them with appropriate special clothing and other personal protective equipment.

The use of new substances and preparations in technological processes is allowed only after the appropriate hygienic standards have been approved in the prescribed manner.

The routes of movement of vehicles across the territory should exclude cases of their collision, collisions with workers and vacationers.

Technological processes should be based on the consistency of work and equipment, which eliminates the possibility of hazardous production factors.

3. General safety requirements

The instruction contains labor protection requirements for workers of all professions engaged in the repair and maintenance of equipment and crop farms.

All newly hired employees are allowed to work only after passing a medical examination, introductory and primary (at the workplace) briefings with a signature in the register of ongoing labor protection briefings.

In the future, employees are re-instructed and tested on labor protection no earlier than once every three months and periodic medical examinations in accordance with the order of the Ministry of Health of the Russian Federation.

Employees associated with the performance of work or maintenance of facilities (installations, equipment) heightened danger, as well as objects controlled by state supervision bodies, must annually undergo course training and testing knowledge on labor safety.

An employee who has successfully passed the knowledge test is issued a certificate for the right to work independently.

Employees and those who have a break in the work for which they are hired for more than 3 years, and increased danger - more than 12 months, must undergo training and testing knowledge on labor safety before starting independent work.

When changing the technological process or upgrading equipment, fixtures, transferring to a new temporary or permanent job, violation of safety requirements by employees, can lead to injury, accident or fire, as well as during breaks in work for more than 30 calendar days, the employee must undergo an unscheduled briefing.

In the process of production activities, workers are exposed to the following dangerous and harmful factors:

Moving machines and mechanisms;

Moving parts of production equipment;

Collapsing construction materials;

flying fragments;

Increased dust and gas contamination of the working area;

Increased noise and vibration in the workplace;

Increased or decreased air temperature of the working area;

Reduced or reduced air mobility;

Insufficient illumination of the workplace;

Surfaces of equipment, machines and materials contaminated with chemicals, radiation and pesticides;

Exposed rotating and moving parts of machines and
equipment;

slippery surfaces;

Clutter of the workplace with foreign objects;

Rest in unspecified places;

Performing work while intoxicated.

Maintenance and repair of machines and equipment operating in the zone of radioactive, chemical contamination, pesticide contamination and neutralization of contamination is not allowed.

On workplace persons who are not related to the work performed are not allowed. Do not outsource your work to others.

Obey the safety signs.

Do not go behind electrical equipment fences.

Be attentive to warning signals lifting machines, cars, tractors and other types of moving vehicles.

A worker who has committed a violation of the requirements of the labor protection instructions may be subject to disciplinary liability in accordance with the rules of the enterprise, and if these violations are associated with causing material damage to the enterprise, the worker also bears financial responsibility in the prescribed manner.

4. Safety requirements before starting work.

Put on overalls and other personal protective equipment established for this enterprise.

Clothing should be buttoned up and tucked in, pants should be over shoes, cuffs fastened, hair tucked under a tight-fitting headdress.

Check that the tools and fixtures used during work are in good condition, not worn out and meet safe conditions labor.

Wooden handles of tools should be made of seasoned hardwood and tough wood, smoothly finished.

Now we will not tell how the first was born Soviet lorry and what it cost for the Gaz 53 car to be born in the form in which it is. But light trucks were in an even more difficult situation. A typical situation of those times when products are in demand, but they are not on the counter, was called the sacred word "deficit". With great potential Soviet car industry, the niche of delivery trucks was empty for one reason - everything worked for the defense industry.

The army did not need small trucks, so bread and flowers had to be transported on the same Gaz 53. Naturally, whole rivers of gasoline poured into nowhere, but who cared? The needs of the national economy, which later became a small business, were stubbornly ignored. the only domestic truck with a carrying capacity per ton was the UAZ 450, which was again built on the basis of the Gaz 69 military vehicle.

In the 70s, the issue with such trucks became so acute that, with such a great and powerful material base, the country bought Zuk and Nysa delivery vans from tiny Poland. But even if the whole of Poland rushed to make these vans based on Pobeda, it would still not be able to cover the needs of a huge country. Later they began to buy excellent Avia trucks, made in Czechoslovakia under license from the French company Saviem, but they were not enough. It was easier for the country to pay with free raw materials and energy than to build its own projects for the production of delivery vans.

When the situation had already become critical, by 1986 they began to seriously talk about the need to build their own lorry car. But there was no one to build. tried to build and new car factory in Leninakan, and in Ulyanovsk, and at the Bryansk military plant, but due to a weak engineering base, not a single enterprise was able to build a delivery truck. Then Gaz, contrary to the directive from above, as an initiative and anticipating the impending future wave of competition, makes his own development, relying only on their experience and partly on the Volga units.

The first Gazelle in iron was presented only in 1993 at VDNKh, but no one could even imagine that the plant would pull the production of a car that was so different from their usual Gaz 53 and Volg. In fact, at the initiative of the plant workers at that very difficult time, it was possible to create an assembly line literally in a year, and already in 1994 the first Gazelle Gaz 3302 left the gates of the plant. The entire vast post-Soviet market greedily accepted new car and still does not let go, although the design of the model is almost 30 years old. Now let's see what Gas 33021 is in technical terms.

When we talk about the technical characteristics of Gas 33021, there is no need to talk about the breakthrough and triumph of technology. The car owes its birth first of all to the skillful management of the plant, and only then - to designers and technologists. Although they have done a lot. This table with technical indicators Gazelles are not at all a reason to be proud of a car of the early 21st century, since even the same hard-working Ford Transit is a cut above. Nevertheless, this is the first small-tonnage car designed by the Gaz automobile plant on its own.

All cars of the Gazelle family have common features:

Engines for Gazelles were redesigned from the low-power Volgovsky ZMZ 406, there are quite a few modifications and degrees of deforcing of the motor, as well as modifications of the Gaz 33021 car itself, the photos of which we presented on the page.

Model 33021 is perhaps one of the most popular and widespread modifications of the Gazelle. This is a standard Gazelle chassis with an onboard platform and folding sides. cars were equipped only with ZMZ 402 engines. The motor is unpretentious in operation, has 90 horsepower and is easy to maintain. The specifics of the work of an onboard vehicle is such that it does not require particularly high power and traction.

Car modification - Gazelle with a reduced area of the onboard platform, but with an enlarged cabin. In Europe, such cabin options are called crew-cabine. This is an ideal option for transporting mobile assembly and other teams. In addition to the design of the cab and platform, the car is no different from the base model.

As for used Gazelle cars, depending on the year of manufacture, a tilt board can be bought from 300 thousand, but it is important to evaluate the car's mileage.

Despite the fact that they are now actively buying Gazelle Next, 33021 is fully consistent with its price in terms of functionality. Great working car for modest means. He owes his appearance only to the initiative of the factory workers, and the consumer appreciates his stable interest in the model.
